Workplace Investigations

Workplace suspensions in Ireland are a contentious issue and can result in an employer defending injunction proceedings in the High Court before an investigation has started.

In the case of Governor and Company of the Bank of Ireland v Reilly, the judge stated: “The suspension of an employee, whether paid or unpaid, is an extremely serious measure which can cause irreparable damage to his or her reputation and standing."

In the 2023 case of O’Sullivan v HSE, the Supreme Court held that the Health Service Executive acted fairly and reasonably as an employer in suspending a consultant doctor after he had performed experiments on patients without their consent. This ruling overturned the Court of Appeal's earlier decision that previously found the suspension to be unlawful, as the consultant did not represent an immediate threat to the health of patients.

The Supreme Court considered whether the employer's decision to place the consultant on administrative leave met the test set out in the English case of Braganza v BP Shipping Limited & Anor. In that case, the court held that the decisionmaker's discretion would be limited "by concepts of good faith, honesty and genuineness and the need for absence of arbitrariness, capriciousness, perversity and irrationality."

In relying on the principles set out in the Braganza case, the Irish courts have reinforced the right of a decision-maker in an employment context to have discretionary power when implementing a suspension and that any decision to do so must be made honestly and in good faith. Employers should obtain legal advice when considering whether to suspend an employee in any circumstance.

It is possible to suspend an employee during a workplace investigation.[1] While there are no limits on duration, the employee will remain entitled to full pay during this time.

In the UK, suspension is not seen as a neutral act, so should not be a default approach at the start of an investigation. It may be appropriate if, for example, there is a risk to the health and safety of the employee in question (or any other employee), a risk that their continued presence in the business could prejudice the investigation, or risk of continued wrongdoing.

The employer should always check the individual’s employment contract to see if it contains the power to suspend. Suspension should generally always be with pay to avoid any breach of contract. It should also be regularly reviewed and kept to a minimum duration.

Employers should not suspend employees under investigation as a knee-jerk reaction to bare allegations. There must be at least some evidence to support the need for suspension (which may require a preliminary investigation before deciding to suspend). Alternatives to suspension should always be considered, such as a temporary transfer to a different area of work, if the employee agrees or it is otherwise permitted by their contract.

If authorities such as regulators or prosecutorial agencies are involved in the investigation, they may have an opinion about an employee’s suspension, particularly if they wish to conduct interviews. Consider whether or not to involve the authorities in the suspension discussions at an early stage.

ACAS have produced a guide to suspension during investigations (last updated Sept 2022) which gives further guidance on these issues.

It would be difficult to assert privilege over materials that relate to the investigation itself.

Privilege may arise before the instigation of an investigation where an employer may seek legal advice from their legal advisors over the initial complaint and appropriate next steps. Subject to the relevant tests being met, Legal Advice Privilege arises in respect of a confidential communication that takes place between a professionally qualified lawyer and a client. Who the client is will be of significant importance as they must be capable of giving instructions to their lawyer, on behalf of the employer. Caution should be exercised by employers if advice to "the client" is disseminated further within the business to other members of management. If such a scenario arises, then there is a risk that privilege may be waived and such material could be disclosable under a data subject access request. Litigation privilege arises with respect to confidential communications that take place between a lawyer or a client and a third party for the dominant purpose of preparing for litigation, whether existing or reasonably contemplated.

It is also prudent to consider whether an external investigator should have access to their own independent legal advisor, and the funding arrangements for such advice would have to be considered by the employer.

As outlined above, all employees generally have the right to know whether and what personal data is being or has been processed about them (article 8 paragraph 1, Swiss Federal Act on Data Protection; article 328b, Swiss Code of Obligations).

The employer may refuse, restrict or postpone the disclosure or inspection of internal investigation documents if a legal statute so provides, if such action is necessary because of overriding third-party interests (article 9 paragraph 1, Swiss Federal Act on Data Protection) or if the request for information is manifestly unfounded or malicious. Furthermore, a restriction is possible if overriding the self-interests of the responsible company requires such a measure and it also does not disclose the personal data to third parties. The employer or responsible party must justify its decision (article 9 paragraph 5, Swiss Federal Act on Data Protection).[1]

The scope of the disclosure of information must, therefore, be determined by carefully weighing the interests of all parties involved in the internal investigation.

There are two limited types of privilege which may be relevant to investigations:

• Legal Advice Privilege (LAP), which protects communications between lawyers and their clients provided they are confidential and made for the dominant purpose of obtaining or giving legal advice; and
• Litigation Privilege (LP), which can extend to communications between a lawyer and client or third parties, but only where the dominant purpose of the communication is to prepare for or conduct existing or contemplated litigation.

If the relevant tests for privilege are met and apply to materials generated in the course of the investigation, the employer retains greater control over their subsequent disclosure to third parties. The materials would, for example, be protected against disclosure in any subject access request under the DPA 2018.

That said, privilege can be difficult to maintain in investigations, particularly where litigation is not active or in contemplation. Interview notes and witness statements may not attract privilege, particularly if these were conducted with employees who do not fall within the narrow definition of “the client” for LAP purposes (which is limited to employees who are capable of seeking and receiving advice on behalf of the employer).

If privilege applies to investigation materials, the investigator should keep tight control on what documents are created and how they are circulated, to avoid inadvertent disclosure and potential waiver of privilege.

Bear in mind that even if privilege applies to certain investigation materials, there may be a need to create disclosable documentation at a later stage, particularly if there is a decision to instigate disciplinary action.
